Companies have also found there’s room for far more niche offerings beyond the vending machine or huge in-house cafeteria. “What LeanBox is really interested in is having the experience of a gourmet cafeteria, but to make it feasible for an office of 75 or 100 or 300,” says the company’s cofounder and chief executive, Shea Crowley. And technology means a more targeted experience for each office — LeanBox’s “smart” refrigerators can track the kinds of food that employees enjoy most, and the company has seen such a strong response from its clients that it recently launched Grind New England, sourcing hot beverages and kegs of cold-brewed coffee.
